A man has been arrested after setting a car on fire and stabbing three people – one fatally – in central Melbourne, Australia. The attacker was shot by police after confronting officers on a busy city street, authorities said. He was taken into custody in a critical condition. The two survivors were taken to hospital – one in a suspected critical condition. Police said they were “not looking for anyone further at this early stage”. It was too early to say if the incident was terror-related, they said. Officers were initially called to reports of a car fire near Bourke Street, a busy thoroughfare, at about 16:20 local time (05:20 GMT). “As they got out of the car, they were confronted by a male brandishing a knife and threatening them,” Supt David Clayton said in a news conference. “At the same time, passers-by were calling out that members of the public had been stabbed.” Police said the scene had been cordoned off, and it was being “made safe” by a bomb response unit. Footage circulating on social media shows a vehicle, which appears to have crashed into shop fronts, on fire.
